Help with mapnik plugin

[carrbrpoa]

Hello!

I just installed tilestrata and am trying to use it to render maps where it's data comes from Postgis and it's style comes from mapnik XML (generated by Carto in another solution test - by the way, I'm trying to replace gopnik of that solution for tilestrata, because I know node.js better).

So the server is up (with some warnings), /health is Ok ({"ok":true,"version":"2.1.0","host":"osboxes","uptime":"15 minutes, 20.149 seconds","uptime_s":920.15}) but when I put together a Leaflet application to try the maps generated, it just gives me NOT FOUNDS (404):

1.png:1 GET http://localhost:9999/basemap/2/0/1.png 404 (Not Found)
3.png:1 GET http://localhost:9999/basemap/2/0/3.png 404 (Not Found)
3.png:1 GET http://localhost:9999/basemap/2/1/3.png 404 (Not Found)

9625.png:1 GET http://localhost:9999/basemap/14/5857/9625.png 404 (Not Found)

and so on. My tilestrata server code:

var tilestrata = require('tilestrata');
var disk = require('tilestrata-disk');
var sharp = require('tilestrata-sharp');
var mapnik = require('tilestrata-mapnik');
var dependency = require('tilestrata-dependency');
var strata = tilestrata();

// define layers
strata.layer('basemap')
    .route('*@2x.png')
        .use(disk.cache({dir: '/var/lib/tiles/basemap'}))
        .use(mapnik({
            pathname: '/home/osboxes/dados_container_renderer/stylesheet_localhost_pg.xml',
            tileSize: 512,
            scale: 2
        }))
    .route('*.png')
        .use(disk.cache({dir: '/var/lib/tiles/basemap'}))
        .use(dependency('basemap', '[email protected]'))
        .use(sharp(function(image, sharp) {
            return image.resize(256);
        }));

// start accepting requests
strata.listen(9999);

It seems that it's not even scratching server, since no terminal entries are being generated.
Am I missing something?

Thanks a lot!

.use(dependency('basemap', '[email protected]'))

This line should be: .use(dependency('basemap', '*@2x.png')). Hope this helps!

[carrbrpoa]

It does, @brianreavis, thanks! 💯

After that, I observed that the path designated for storing cache contains only some few png for zoom level 14 (I guess), but I already zoomed and panned the map a lot. Any ideas about that?

[brianreavis]

I'm not sure this will fix what you are experiencing, but could you update tilestrata-dependency to 0.5.1? Just noticed it wasn't quite set up to handle the relatively-new filenameless routes (which could lead to some weird behavior).

[carrbrpoa]

It worked @brianreavis, thanks a lot!

One last thing (:P): when I try /profile, server stops with:

/home/osboxes/tilestrata/node_modules/tilestrata/lib/TileServer.js:340
				plugin_name: getplugin(plugin, layer, file).plugin.name || '',
				                                           ^

Do I need to do something? Thought it should come by default.

Thanks again!

[brianreavis]

Hah, embarrassing. Good catch! Just released a patch for that: https://github.com/naturalatlas/tilestrata/releases/tag/v2.1.2

[carrbrpoa]

That's it, thanks for your work, @brianreavis, it's really nice!

When I try return image.resize(256).quality(80).webp();, as seen in sample I get error 500. How can I figure out why? Only with return image.resize(256); it works.

@brianreavis There are any logging available?
